Why did we EVER think antimatter exists?

What is antimatter? Who discovered antimatter? How was antimatter discovered? Why do we never really see antimatter?
In this video we’ll talk about Paul Dirac, Carl Anderson and Arthur Shuster, and their contributions to the discovery of antimatter. We’ll discuss annihilation, pair production, cloud chambers, rant about antimatter bombs and more!

Further research you can do:
A video by Dr Becky - “Where is all the antimatter? | Unsolved Mystery in Physics” shows experiments done with antimatter and gives a tour of the Antimatter Factory and the LHC (Large Hadron Collider) at CERN.

“What If You Explode An Antimatter Bomb On Earth?” by Riddle- talks more about antimatter bombs.

OK, after spending waay too much time looking into it, now I am reasonably sure that the "there is nothing to be discovered" quote comes from Michelson in 1894.
Baron Kelvin gave a lecture at the Royal Institution in 1900, a kind of "state of the Sciences" speech, called "19th century clouds over the Dynamical Theory of Heat and Light"
Is striking what challenges he identified for the future:
the question of the luminoferous Esther.
the question of the black body radiation.
Note that, to answer these, "only" Special and General Relativity, and Quantum Mechanics had to be developed. Not bad for the old geezer!
Some sources, if somebody want to follow me by the rabbit hole I falled into:
the wikiquote and wikipedia Pagés about William Thomson,
The actual lecture at the RI:

Also, I found that Dr. Robert Mcnee addressed all my doubts right at the end(sigh...), so I will shamelessly proceed to copypaste his twitter thread:

"There is an apocryphal story about the great physicist William Thomson — Lord Kelvin — in which he surveys the state of physics at the end of the 19th century and judges it nearly complete.
Likewise, comments attributed to the physicist Albert Michelson (especially in an 1894 speech) suggest that he thought there was very little left to do in the field, except perhaps take more detailed measurements of various properties of matter
These stories are always a set-up for a punchline: Physicists of the era thought the fundamental questions had all been answered, when in fact there were deep and fatal problems with their theories. Perhaps they were too attached to familiar ways of thinking to notice
It may be that Kelvin made some comment that, over the years, was transformed through retelling into the sort of story outlined above. But we don’t have to wonder what he really thought about the state of physics as the 19th century drew to a close
Lord Kelvin clearly laid out two significant problems that physics did not know how to address in his lecture "Nineteenth-Century Clouds over the Dynamical Theory of Heat and Light, ” delivered to the Royal Institution of Great Britain in 1900.
His lecture begins "The beauty and clearness of the dynamical theory, which asserts heat and light to be modes of motion, is at present obscured by two clouds.”
The first cloud is the question of the lumineferous ether, the hypothetical medium that most 19th century physicists assumed was necessary for the propagation of light and other forms of electromagnetic radiation
But by 1900, physicists had spent almost 13 years wresting with the null result of Michelson and Morley. As far they could tell, there was no ether. Attempts to explain away the non-detection were becoming increasingly convoluted.
His discussion of the second cloud begins with an examination of the kinetic theory of gases. Lord Kelvin is troubled by a number of problems that follow from the equipartitioning of energy among the various modes of a gas.
This idea, when combined with what was known at the time about thermodynamics and electromagnetism, leads to a paradox: The total energy emitted by a blackbody in thermal equilibrium seems to be infinite. In 1911 Paul Ehrenfest would dub this the “ultraviolet catastrophe."
(This was not Kelvin’s specific complaint, but it is probably the most dramatic consequence of the ideas he was wrestling with.)
Again, Kelvin sees a collection of challenges that physics, as it was understood at the time, had not been able to answer.
What is interesting about Kelvin’s lecture is that the two problems he sees as clouds hanging over physics are precisely the problems that required the revolutionary new ideas of the early 20th century for their resolution.
Einstein takes the null result of Michelson and Morley seriously. Eliminating the ether implies that the laws of electrodynamics hold in all inertial frames, which means that all inertial observers measure the same speed of light. This leads him to special relativity.

Planck’s claim that matter emits radiation in discrete chunks, further refined by the founders of the old quantum theory and revealed as the reality of light by Einstein, cures the ultraviolet catastrophe by fundamentally altering the microscopic accounting of blackbody emission.
So Kelvin (and many of his colleagues) were not oblivious to the problems facing their theories; they were acutely aware of them and struggled with their resolution.

Is so nice to be appreciated! I will be back with a proper comment when I pick myself from the floor, ;)))

Your channel is growing sooo fast!! I am sooo happy for you and you deserve all of them we all can see how much effort you put into them also I am little late (sorry for that). Tysmm for the video!!

[richwright]

Hi, really like the videos, interesting flow and editing, very good narratives. My only suggestion is that some of the editing cuts are a bit quick, and that you speak very fast, so perhaps give yourself a little more time and think about cutting between images just a little slower. I think it's pitched perfectly for someone curious about science, and it's very engaging, entertaining and amusing. Well done, keep up the good work and spread the joy of physics.

Your channel good. Make more video please.

you should have said like charges

what is dr.becky doin here?
i mean what was the reference

[CIS-ms]

Could it be that due to that it is to simple to be affected or maybe so small there in there own space since we can't see with light and time is unable to be conceived in such a space thus never affecting them and make up things in not a structure but a harmony.
